What this Trial Is About
Researchers are evaluating lifestyle interventions to address overweight and obesity among taxi and for-hire vehicle (FHV) drivers, a mostly immigrant, minority, and essential worker population with higher obesity rates than the general public. The study uses a hybrid design combining effectiveness and implementation research to develop and optimize a scalable intervention using the Multiphase Optimization Strategy (MOST). This trial focuses on four behavior change components based on Social Cognitive Theory. Participants are randomly assigned to one of eight groups receiving different combinations of four intervention components: in-person individualized diet and physical activity counseling, thrice-weekly diet and physical activity text messages, weekly telephone support, and self-monitoring tools for diet and weight. The study also includes focus groups and interviews conducted in Spanish, with data collected through surveys, dietary assessments, and step count tracking using personal devices or pedometers. During the study, participants engage in various assessments including weight measurements at baseline and 12 months, process evaluation questionnaires, and cost-effectiveness estimation up to 6 months. Study staff collect and upload step count data and dietary survey responses, with follow-up conducted by phone when needed. The total participation time includes up to 12 months for weight and evaluation outcomes, ensuring monitoring of intervention feasibility and impact.
